Miriam Leslie (née Follin; after first marriage, Peacock; after second marriage, Squier; after third marriage, Leslie; after fourth marriage, Wilde; claimed title, Baroness de Bazus; June 5, 1836 – September 18, 1914) was an American publisher and author. She was the wife of Frank Leslie and the heir to his publishing business, which she developed into a paying concern from a state of precarious indebtedness. After her husband's death, she changed her own name to his, Frank Leslie. She made Carrie Chapman Catt a residuary legatee of her estate, to support enfranchising women. The activist established the Leslie Woman Suffrage Commission for this purpose.
